Why not both. While you are attending school study for and take A+ You'll be a step ahead of the average techy fresh out of college. IMO an Associates degree does just fine when looking for a job. I only have AAS and A+ and I'm doing fine. If I wanted to take my career to the next level I have a great foundation already. I would just need to brush up on some lost skills and study, maybe take a couple side classes, and BAM im ready to move on.
Good luck with your choices.
